SPECIFICATION forming part of Letters Patent No. 707,953, dated August 26, 1902.

Application filed October 17, 1901. $eria1 No.79,010. (N0 specimens.)

T0 aZZ whom it may concern:

Be it known that I, HORACE S. BLINN, a citizen of the United States, residing at Omaha, in the county of Douglas, State of Nebraska, have invented or discovered a new and useful Improvement in Depilating Compounds, of which the following is a specification.

My invention or discovery relates to depilating compounds; and the object thereof is to provide a compound fol-removing superfluous growths of hair from the human body and to kill the roots to prevent subsequent growth of hair, but without injuring the skin.

My compound consists of calcium oXid or quicklime in the proportion varying from eighty to ninety-two parts, mixed, preferably, with equal quantities of arsenic disulfid (AS252) and arsenic trisulfid (AS-2S3) to form the remaining twenty to eight parts-that is to say, the arsenic sulfid employed consists, preferably, of about equal quantities of disulfid and trisulfid, while the lime preferably forms eighty to ninety-two parts of the compound. To permanently kill the hair fol licles or roots, powdered hyposulfite of soda is added to the ingredients just mentioned in such quantity as to form about ten per cent. of

the entire compound. By preference a perfume, such as orris-root, will be employed to deaden the odor of the compound. This ingredient, however, is not essential and is without effect upon the skin.

The method of using the above-described compound is to make a paste by mixing the calcium oxid and arsenic sulfid with water, and this paste is then spread over the surface from which the hair is to be removed. After the lapse of from ten to forty minutes the paste may be removed by scraping the skin with a smooth blunt instrument, as a bone or wooden spatula, when the hair will come off with the paste. The surface of the skin is then cleansed thoroughly with pure water without the use of soap and subsequently dried. WVhen used in this manner, the hair will be completely removed without harm to the most delicate skin.

WVhen a compound is desired which will permanently kill the hair roots or follicles, powdered hyposulfite of soda is added to the calcium oxid and arsenic sulfid in such quantity as to form, preferably, about ten per centum of the entire compound. The method of using this compound, comprising hyposulfite of soda, is the sameas above described; but the application should be repeated two or three times Weekly, the strength of the hair becoming less and less after each application. After a series of applications the hair ceases to grow, the necessary number of applications varying with the strength of the growth of hair. The skin instead of being discolored or otherwise harmed by the use of my compound is rather softened and tends to become whiter and clearer than previous to the application.

What I claim as new, and desire to secure by Letters Patent, isl 1. The herein-described composition of mattor for removing superfluous human hair and preventing the subsequent growth thereof, the same consisting of calcium oXid or quicklime, arsenic sulfid and hyposulfite of soda, in substantially the proportions stated.

2. The herein-described composition of mat ter for removing human hair and preventing the subsequent growth thereof, the same consisting of about eighty to ninety-two parts calcium oxid, eight to twenty parts of arsenic sulfid and ten parts sulfite of soda mixed with water to form a thick paste.
